1. Summary of Results: a. In the experiment, dilutions of .4M A(NO 3 ) 2 and .4M B(NO 3 ) 2 were made in a well plate. Once the dilutions were made 10 drops of K 2 X were added to each of the four dilutions of A(NO 3 ) 2 , and 10 drops of KY were added to each of the four dilutions of B(NO 3 ) 2 . Then each well was observed to note if precipitation occurred. These results of whether or not precipitation occurred were used to find the solubility product constant (k sp ) range. b. The k sp range for AX was between .2M and .1M because the actual k sp is found between the concentrations when precipitation occurs and when precipitation does not occur. Q sp (non-precipitate) < K sp < Q sp (precipitate) Mixture: A(NO 3 ) 2 + K 2 X Drops of K 2 X Precipitation .3M 10 Precipitate .2M 10 Precipitate .1M 10 No Precipitate .05M 10 No Precipitate c. The k sp range for BY 2 was between .025M and .0125M because the actual k sp is found between the concentrations when precipitation occurs and when precipitation does not occur. Q sp (non-precipitate) < K sp < Q sp (precipitate) Mixture: B(NO 3 ) 2 + KY Drops of KY Precipitation .1M 10 Precipitate .05M 10 Precipitate
